Susan M. Karl, Paul W. Layer, Anita G. Harris, Peter J. Haeussler, Benita L. Murchey
2011, Professional Paper 1776-B
The Cannery Formation consists of green, red, and gray ribbon chert, siliceous siltstone, graywacke-chert turbidites, and volcaniclastic sandstone. Because it contains early Permian fossils at and near its type area in Cannery Cove, on Admiralty Island in southeastern Alaska, the formation was originally defined as a Permian stratigraphic unit. Similar...
